Abstract
Official abstract text for this publication.
A system including a transmitter and a receiver that are loosely synchronized, the transmitter encodes signal waveforms having a start time, a width and a height that are determined based on a range of possible relative drifts of a receiver clock with respect to a transmitter clock and the receiver decodes the waveforms based on a sequence of tests, chosen to account for any uncertainty that may arise due to the lack of tight synchronization.
First claim
Opening claim text (preview).
We claim: 1. A transmitter configured to communicate a first one of a plurality of messages to a receiver having a receiver clock, the transmitter comprising: a transmitter clock configured to generate a clock signal that controls timing of the transmitter, a timing of the transmitter clock running independent of a timing of the receiver clock; and a modulator including a processor configured to, determine a start time, a width and a height of a pulse representing the first mes…
